enlarge or reduce the image with respect tothe size of the'subject.

Another object of the invention is to provide an enlarging and reducing reproducing apparatus which includes a housing having an adjustable object holder therein, a com-' bined ens and light carrier adjustablymount- :0, ed with respect to said object holder to enable the focusing of thelens with res ect to the object, a mirror onto which the o ject image is reflected, and an adjustable image receiving table for varying the'size of the reflected 26 image received thereon in its natural form from said mirror, the said table being disposed at a forwardly inclined angle for-comfort and convenience of a user in tracing the reflected image upon a sheet of translucent to paper.

With these and other objects in view, the invention resides in certain novel construction and combination and arran ement of parts, the essential features of whi are herepointed out in theappended claims, and are illustrated in the accompanying drawing, in which Figure 1 is a side elevational view ofour' Figure, 5 is a vertical transverse sectional view on the line 5-5 of Figure 1.

Figure 6 is a horizontalsectional view on the line 6-6 of Figure 1. I

inafter fully described, are particularly nal sectional view on the line 4-4 of Figure 3.

Figure 7 is a "ertical transverse sectional view on the line 7-7 of Figure 2.

Figure 8 is an enlarged detail horizontal sectional View on the line 88 of Figure 1.

Referring to the drawing by reference characters, the numeral 10 designates our improved reducing and enlarging apparatus in its entirety and which includes a rectangular or box-like housing 11 supported at its four corners-by legs 12. The top of the housing adjacent the rear thereof is provided with an opening 13 by which'access may be had to the interior for the purpose of inserting andre moving the object or drawing tobe enlarged or reduced. A hinged door 14 is provided for closing the opening 13 under normal working condition. The top of the housing at the front thereof i inclined downward as at 15 and is rovided with an opening 16 to the walls 0 -which one end of a flexible casing 17 is connected, the said casing 17'being in the form of a bellows and capable of expansion and retraction for apurpose to be presently explained. The outer end of the flexible casing 17 is connectedto a work table 18 having an opening 19 therein and which onening is closed by a transparent glass panel 20. The work-table 18 is thereforedisposed parallel to the inclined portion 15 of the top which provides a convenient work-rest and also enables an operator to sitat the table and assume a comfortable position. 7 i

For supporting the work table in an adjusted position and for guiding the same in its movements to unadjusted position, frames 21 are fixedly attached to opposite sides of; the same and which frames straddle the sides of the housing 11. Each frame 21 includes outer parallel legs 22 and a central intermediate longer leg 23. .The leg 23 is provided with a longitudinal slot 24 and the outer side edge is provided with rack teeth 25. Housing plates 26 are fastened to opposite sides of the housing 11 and are provided with channels27'for accommodatingthe legs 22 and a central channel 28 for receiving the leg 23 of each frame. J ournalled in the side walls of the housing 11 and extending transversely thereof is a shaft 29, one end of which extends through one of the hous ing plates 26 and which end is provided with a manipulating knob 30. Fixed to the shaft 529 and disposed beyond the side walls of the housing are driving gears 31 which constantly mesh with driven gears 32 mounted on stub shafts 33 ournalled in the side walls of the housing. These driven gears 32 in turn mesh with the rack teeth on the legs 23 depending from opposite sides of the worktable whereby manual turning of the knob will cause either the raising or the lowering of the work-table depending upon the direction of rotation imparted to the driving shaft 29. The power is transmitted from the shaft 29 through gears 31 and 33 to the leg 23 through the rack teeth 25.

l-Iavin described the means for facilitat ing the adjustment of the work-table, we shall now explain the means by which the worktable may be held in an adjusted position. This means includes bolts extending through the housing plates 26 and side w lls of the housing 11 and also through slots 2% in the legs 23, the inner ends of the bolts being threaded with which nuts 35 co-act, and which nuts are held fast to the side walls of the housing so as not to turn upon turning of the bolts. The outer ends of the bolts have handle members 36 fixed thereto by set screws or the like. The inner faces of the heads of the handle members are pro ided with bearing surfaces 37 which extend through the housing plates for clamping engagement with the outer sides of the legs 23. It will be noted that when the handle members 36 are moved in one direction, a clamping action will be set up between the head of the handle members and the legs 23 and upon turning of the handle members in an opposite direction, the clamping action is released and the table may be raised or lowered to the desired position.

The interior of the housing 11 is provided with a false bottom 38 disposed parallel to the true bottom but in spaced relation with respect thereto. Parallel guide rails 39 are mounted above the bottom 38 in spaced relation tl ereto and which extend forwardly from the rear wall of the housing and terminate on a plane rearward of the opening 16. Slidably mounted upon the guide rails 39 for longitudinal movement is an object support d0 including a vertical panel ll having cars 12 extending from its opposite sides and which ears are slidably mounted upon the guide rails 39. The front side of the panel :1 provided with a bracket 43 which renovably receives a shelf 44con which the ob 'ect to be enlarged or reduced is placed. In the event that the subject matter is a drawing or ihotograph, the same is placed on the bracket a3 and held at its top by a clip or holder l5 mounted at the top of the panel 41.

Journalled in the front and rear walls of the housing 11 and disposed below the false a: ha

bottom 38 are screw shafts i6 and t7, the outer front ends of which carry manipulating knobs l8 and i9, respectively. Fixed to the bottom of the panel ail and depending therefrom is a lug 49 having a threaded bore 50 through which the threaded. portion of the screw shaft 46 extends. The flat sides of the lug 49 freely pass through a longitudinal slot 51 in the false bottom 38 and which slot is disposed directly above the screw shaft -l6. It will be noted that by turning the manipulating knob 48, the screw shaft hi will feed the object support longitudinally within the housing and the limit of movement of the support depends upon the length of the slot 51 as the end walls of the slot act as stops with which the lug d9 engages.

Also disposed within the housing 11 and adjustable with respect to the object support 40 is a lens and lighting assembly which includes a vertical plate 53 terminating in spaced relation to the top and side walls of the housing, and a horizontal rearwardly extending wall 54. The vertical plate 53 supports a projecting lens 55 while the l1o'-.-i zontal wall 54 supports electric lamp sockets 56 which are respectively disposed on oppo O X site sides of the range of the lens and which sockets receive electric light lamps 57. the light from which is adapted to be rcll *ctcd onto the object or subject supported by the object support 41 which reflection is accomplished by mirrors or reflecting surfaces 58. The wires 59 from the lamp sockets 56 lead to an electric switch 60 mounted exteriorly on one of the sides of the housing 11 and to which an electric cord 61 is opcratively connected, the said cord having its free end provided with a fixture plug 62 whereby the plug may be inserted into the socket of a wiring system to transmit electrical energy to the electric lamps and which is controlleiil by the turning on or off of the switch (10.

The space between the top and side edges of the vertical wall of the plate 53 is closed by a flexible shield 63 carried by the said plate and which serves to prevent light from passing forwardly of the lens so that all of the light from the electric lamps is concentrated upon the object support. Extending from opposite sides of the plate 53 are ears (ll through which the guide rails 39 freely extend. Depending from the horizontal,

wall 5a is :1 lug 65 having a threaded bore 66 for acconnnodating the threaded end of the screw shaft t7, the said lug freely extending through a longitudinal slot (36 in the false bottom 38 and which slot is disposed parallel to the slot 51 but extends to a plane forward thereof to enable the lens and lighting assembly to be adjusted to a position forwardof the object support. It will be appreciated that by turning the manipulating knob 49, the screw shaft 47 will feed the lens or lighting assembly in a longitudinal direction with respect to the object support in order to enable the lens 55 to be properly focused with respect to the object to be reproduced.

Mounted at the front end of the housing 11 within the same is a reflecting mirror 67 which is mounted at such an angle with respect to the lens and the transparent panel 20 of the work table so that the image'of the object or drawing to be reproduced is received on the mirror from the lens 55 as to be reflected upon the panel 20 on to the of paper placed on the work table on which the reproduction is to be made. It will be appreciated that by projecting the image upon the mirror instead of directly upon the work table, it will of course permit the image to appear right side up when an operator is positioned at the front of the table.

From the foregoing description, it will be appreciated that the image of an object placed upon the shelf 44 may be projected upon the transparent panel 20 or rather on the sheet placed thereover and the size of the image may either be enlarged by raising the work table with respect to the mirror 67 or reduced by lowering the work-table relative thereto. Although, we do not-wish to limit ourselves to any particular use to which the invention may be put, we find that it is exceptionally useful in the reproduction of shoes and other objects, photographs or drawings.

While we have described what we deem to be the most desirable embodiment of our invention, it is obvious that many of the details may be varied without in any way departing from the spirit of the invention, and we therefore do not limit ourselves to the exact details of construction herein set forth nor to anything less than the whole of our invention limited only by the appended claims.
